Radiation Flashcards
1
Q
Define radiation.
A
Radiation is the transfer of heat energy through electromagnetic waves.
2
Q
How does radiation move/travel?
A
Radiation travels through electromagnetic waves, which move in straight lines. Because radiation does not require particles, these waves are able to travel through space vacuums.
3
Q
Where do the waves take this energy?
A
Electromagnetic waves take the energy to nearby objects/surroundings.
4
Q
Can heat energy be absorbed through radiation?
A
Yes, the heat waves that are emitted may also be absorbed by a colder objected/body.
5
Q
Define absorb.
A
Absorb means to take in.
6
